C 9#5 on Bass (5-String)

C 9#5 spells C – D – E – G# – A#. A bassline treats those notes as a hierarchy — root first for gravity, fifth for stability, then the third and any extensions for color — and the shapes below put each of them under your fingers on the Bass (5-String)'s BEADG strings.

Full chords are optional equipment on bass: down low, stacked thirds turn to mud, so the grips that work keep two or three notes — root-fifth, root-tenth, shell voicings — and the arpeggio is how the rest of the chord becomes a line. The 5-string layout adds a low B to the standard EADG core, so the same shapes reach further without shifting.

Start from the root, play the arpeggio until the sound of C 9#5 is in your ears, then loop it against the progressions in C so the tones become choices instead of charts.
